You should really compare the full specs of the NiMH, the substituted LiPo, and the charger used, to be technically sure. And the load specs, if possible. A 24V charger for NiMH should be cheap, if a...

24 V is 24 V. However also check capacity of the NiMH to make sure it is in the ballpark of 6000 mAh. NiMH should be larger and heavier than Li-polymer for the same capacity. This aside, it should...

I have used quite a lot of TMX in Beutler with excellent results. Could never get quality negs from TMX with D76. Delta 100 should work very well in Beutler!

Fog may be a bigger issue than development time, especially with more sensitive films. I have developed 10-yr-expired film with standard times in D76 1:1, obtaining acceptable images.

Colophony resin is used to give grip to bows' strings in instruments, such as violin or cello. AFAIK it is harmless. You can give it away to a musical school.
