Hi,
No problem with what you propose. Make certain that you remove the covering film if it is an ARF from all but the very edges of the centre ribs to ensure the best contact and ensure that you put plenty of epoxy on the joiner/dihedral brace as well when you bring the two halves together. Any surplus epoxy can be cleaned up with an alcohol soaked rag. (after success you can suck on the rag

).
Use the slowest set epoxy you can find to give you some time to set things up and to allow it to soak into the wood for greatest strength. The slower the set the greater the strength. Most models then require fiberglass reinforcement around the join if you are building a kit.
Cheers,
Colin
