I would think it is possible. You could reflow on a attiny25 and cut the trace at the vdd pin of one 7135. Then run a small wire from the appropriate pin on the attiny25 for the second channel on that single 7135 VDD pin. Toykeeper would be the one to ask. The pins in the firmware could possible be associated wrong on the qlite driver for it to work straight out of the box.
If you use a attiny85 NarsilM or anduril code could possible even work. Toykeeper would know. :wink:
