My initial thought was "No way," but first looks in BB6P say 2245H will work fine.
Subwoof knows where there's a couple available for sale. Paying the freight and acquiring an original to build from would be my suggestion. That way, you can try it out first to be sure, too.
If you do that, prepare detailed construction drawings for the benefit of the forum.
I'm still looking for a 4685 and a 4682. Those smaller ones would also be fun to build. I have a preliminary design for 4685 in BB6P that I may build while the search continues....
