The preference is to have all the batts in the bank the same (size, type, mfr, age), but that is not a good option per the OP. The problem I see here is not that it will not work (it will) but the two types of batt will not age the same. At some point one group will need replacement and the other will still have some life. So he will have to choose to replace all or some and that complicates it further.
Ski, but in a mixed bank they do NOT have the same charging profile. Think about it. That;s why as you mention later, death will be premature.
