Share common wire across 2 timers

My current setup is 2 irrigation timers. One for the back of the house, one for the front. I've purchased a new timer because one of them broke that will support more valves but it doesn't have quite enough to merge all of them onto one timer. Consequently, i want to leave some currently unused valves on the old timer and move some of the other ones to the new timer. My question is can I share a common wire between 2 timers and if so, how would I do so?

For example - Setup Today
Timer 1: F1, F2, F3 valves (all wrapped up in its own irrigation wire with it's own common wire leading to timer 1)
Timer 2: B1, B2, B3 valves (all wrapped up in its own irrigation wire with it's own common wire leading to timer 2)

Intended setup:
Timer 1: F1, F2, B1, B2 (B1, B2, and B3 currently share a common wire so it would have to link to both timer 1 and 2)
Timer 2: B3

Is this possible and if so how? I'm thinking most simple is just splice the common wire from the back irrigation wiring and link it to both timers so timer 1 will have a common wire from the front irrigation wiring as well as the back irrigation wiring but I have no idea of the consequences of doing so.

Sorry if i'm not using proper terminology and thanks in advance.

If you employ a single transformer to feed the two controllers, it should work okay.

Are you referring to something similar to the product link below? I'm trying to visualize how to set this up. Thanks!

You went and bought the controller, so go ahead and try your idea. The worst that happens is that it won't work. If you want a sure thing, you buy the single controller that can handle the entire property.
