But if the problem is separated elements then it won't be a problem to separate

I guess cleaning off old epoxy might be tricky.

I posted a note to the Yahoo camera repair group on re-cementing
elements and got this response

Yes, go here:

If Zuiko used balsam, it should be repairable.
If Zuiko used UV epoxy, well, it may be hard to separate the lens
doublet. Maybe even impossible.
Good luck
