At least in the C84 the chips are just connected in parallel "dumb".
It can not judge which color is in which slot by the chip. All colors must
be present or it will not get the right response when polling for all the
colors, but it does not know the order. I had the chips soldered together
as a stack away from the carriage, for easy (bulk) resetting, before i got
the spongeless carts with auto-reset chips.
They might be very reluctant to fill a different color into the cart,
certainy if they fill through the outlet valve with non-disposeable tools
that could get contaminated. A tiny amount of black can color one heck of
a lot of water, and of course ink.
About the heater, maybe a ceramic rod element like that from a radiation
heater might work well. You'd need to hook it to a dimmer and let it
settle or use feedback control. The hot air gun ought to be a quicker fix
for trials.
