How thick is the ply? IMO you're tanking a big gamble as even thick ply will still flex considerably compared to the glass it is trying to support, which doesn't flex at all, so essentially the ply is doing nothing.
Seems like a big risk to me and a lost opportunity. If it were me I'd be selling that tank (or putting it on another stand made to suit) and getting a wider and lower tank made to fit the stand you have.
