In
TDW NewUI + TDC 2.5.0 there is a user option that you can set so that when you click the Crash Dive UI button it will teleport you to the Radio Room, wait x amount of seconds (5 by default, again an option you can set) then initiates the Crash Dive command. So, there's already a mod that does that.
If you prefer the normal way, you can either turn off that option or simply use the keyboard command which still requires you to be off the bridge, rather than moving you off the bridge for you.
