Theres no way to combine the 2 units, your best bet is to take out the rattler piece and find a quality security system that incorporates a remote starter.  this is by far the best method with little to no headaches.

Absolutely, why combine 2 terds? you just get one big pile with a bad smell and a big headache. Spend your money on a decent combined unit that will function properly from day 1. Trying to interface 2 different mfgs just doesnt always work right. I didn't look at you links but Im sure the bulldog wont do it. [theyr going under anyway why put one of their units in???] , off the rattler [aux out put ch 3] to activate the rs unit, but a bullpuppie wont activate that way , and Im pretty sure a rattler wont have a wire to pulse to disarm it.. SOL. If ya get a DEI unit and you HAVE an aux output third channel, then you could activate a stand alone remote start the is designed to be added on to an alarm.
