The new beta version of Chimera (not the last stable release) does a very good job mutating DNA bases regardless of purine to purine or purine to pyrimidine and vice versa.

I don't see that this means you have to use LEaP to do the modifications. A
lot depends on where your structures (of either end point) come from. If it
is really just a G->A swap on one side, and C->T on the other, you can use
the visual in editor in LEaP (or lots of other programs) to make a few
changes, then save the pdb files.
...good luck...dac
