Emergency Start Button - Connects both Battery banks

Howdy, I am thinking about changing my emergency start swtich from the stock momentary type to a single pole, single throw, switch with a hinged cover. Want to have the option to draw from the engine...

On my rig the momentary switch energizes a relay that ties the two battery systems together temporarily.
After my chassis engine starts the same relay is energized to charge the house batteries.
The idea of the momentary operation, is to allow the electronics to take over.
Putting a non-momentary switch in could cause other issues in the battery control center.
I would not do it as we do a lot of dry camping away from any help.
