yes, a long flexible airstone that can be attached with suction cups, creates lots of bubbles, and if you get one of the betta laser setups, you can make em glow, and it doesnt end up costing much either
thats what id do for more DO
if you dont like the way it looks, place it halfway up the back, so you can have the nice bubbles, and the other half you can clearly see fish
your project looks completely do-able, just figure something out for the filter
on a side note, make sure to not get all the fish that are topswimmer's
