Dual fuel soaked charcoal canisters

[Willi2ds]

So I've searched and couldn't quite find what I was looking for. I have two canisters, I'm assuming that's because I have dual tanks. The bottom of both of these are saturated with gas, first thought was to remove them both but I really don't want the garage smelling of gas all the time. So my questions are:
Can I just do just one canister and use tees to join the tank vent lines?
Has anyone used one successfully out of a newer vehicle?
Rebuildable? I've heard of cutting apart and using fish filter charcoal and regluing, not sure how durable this would be.
If nothing else, any fairly cheap replacements?
Thanks guys

From the 1979 Light Truck Service Manual; here is the entire section on the Evaporative Control System - as it was known back in the early years.

In 1979, there were 72 variations of emission control systems - for the C/K 10-30 series. After matching for engine size/GVWR and eliminating high altitude/CAL applications, only five choices remained. Out of the remaining five designs, just three applied to trucks with the dual tank option. They are shown below. They look to be identical to the single tank version - except for some additional hoses and the extra canister:
