Combining Dissimilar Battery ah?
I know there are a few people here with real-world experience with this, so I hope they chime in! QUESTION: With a small 12v AGM battery (33ah), I have the choice of paralleling a slightly larger ...

Gassing is neither normal, required, nor necessary with AGMs. It is the improper application of excessive volts that force current and causing the unwanted gassing that may cause the problems.
I use temp-comp chargers with my AGMs because I prefer unattended charging with an actual cable-on-the-post RTS sensor. If the AGM battery is getting warm enough for gassing, the RTS tells the charger to roll back the Volts. This in turn, automatically lowers the current that is heating the battery. I believe this is optimal.
I have measured AGM temps from 6F to 110F and the Volts were automatically adjusted with the RTS cables.
