I'm going to go against the grain and say if you only add your current fish with some good filtration the 150 might work, though if your srd is like mine forget it.

SRD?

I am going to have a couple of hiding spots as well, interestingly everyone seems to get along pretty well with the exception being the Oscar and the "Texas" and even they mostly posture. I am thinking about using silicone to attach some slate shelves to the tank and create some vertical seperation as well.

That's a heavy bioload for a 150. It may work, nitrates will probably be a problem due to the volume of water. Just think, an adult Oscar needs at least half of that 150g for him self alone at a bare minimum.

Oscars and other large cichlids produce a huge amount of ammonia which in turn equates to a ton of nitrates. I'd say go for it. Monitor your nitrates and reduce stock if needed. That or do more water changes. Your more likely to lose fish due to nitrate poisoning than ammonia. But hey they are in a 60g so anything is a welcome upgrade for them.

I've kept an Oscar with other fish before, maybe I was lucky but he ignored anything that was to big to fit in his mouth. JD's on the other hand seem to have more aggressive behavior from my experience.

I think since they all grew up together may be the only reason they can tolerate each-other.

Glad you are getting them a nice size tank! How big are the fish now? A lot of people will say the 150g tank is still too small, but I have to say I think it is ok, (at least for now), if they have been coexisting in a 60g. Very few people who get fish that are too big for their tank ever actually upgrade, so I think you deserve props for doing a significant upgrade even if it is not the very most ideal size, it is a heck of a lot better than a 60g and a heck of a lot better than most large cichlids from big box stores will ever get, tbh. Just keep up on WC, watch nitrates and PH, and pull any individual fish that starts causing problems.

I am planning to add some Clown Loaches, Electric Blue Jack Dempseys, and Geophagus in the future.

I have heard EBJD don't do well with normal JDs (I have only the normal kind, so no first hand experience). I would only get the clown loaches if you can find some that are already large, or they will end up getting eaten again because loaches usually grow very slowly compared to cichlids, ime. Maybe consider Pictus catfish instead? Or a single larger Syno or dwarf giraffe catfish? Same with Geophagus... or maybe consider something like Firemouth or 'Geo' steiny instead. I think the normal Geos tend to be a bit fragile when young.

They are currently pretty small likely due to the tank size, I had planned on getting them a larger tank sooner but funding did not allow
Jack Dempseys 4.5-3.5"
Oscar 6"
Texas Large 6"
Flowerhorn 3.5"
Pleco 7"

The plan is to grow the Loaches in a separate tank and add them in, like you said they seem to be slow growers, they are one of my favorite fish because they are so fun to watch, it was pretty horrifying to get home and see fin sticking out of the oscars mouth, I thought they where large enough...

SRD = super red dragon flowerhorn. I will say moving them to a larger tank may actually spark some fighting over new territory, but again out of those fish the only ones that I have experience as being killers are flowerhorns. Like I said I'd ditch one JD or both if you are adding an ebjd. Instead of clown loaches that get quite large and prefer large groups I'd go with a harder catfish/pleco. Sorry if I missed this, but what are you filtering with?

Currently I have a sump and a marineland 350 hob, the new setup will have a much larger higher flow sump with a wet dry section.

With those and this stocklist
1 Jack Dempsey
Oscar
Texas Large
Flowerhorn
Pleco

You probably could add a couple geos OR a few clownloaches OR another 12" fish. To me the issue is not the bioload, just possible aggression from the flowerhorn. Really in my experience the other fish aren't that aggressive as far as cichlids go.

Usually there is not much else to claim for territorial when in small tank, when given them a big nicer house then there is worth something to fight for then it's create a problem.
