Just using a tank emitter would work... or fail ethier one
You might as well go edit the mini-nuke because it's explosion is derived from the tank one with all the debris and everything.
If all you want is higher damage/brick damage and radius damage you can do all that by editing about 8 lines in the script, it would take you 30 seconds to find them and 10 seconds to change their values to "999999999" or whatever you want.
