is it possible?

either a weapon or countermeasure that when fired it opens up into a jump hole? so u can pass through..
obviously the cordinates would have to be preset but would b good for clans..

heres my theory of it workin..

when in fight u become out numbered, fire wep/counter measure, gate appears, jump through back to clan base where u have heavy wep platforms so anyone following is blown up on sight as they try and follow through..

if someone can give me an insite on how to merge a jumpwhole with a countermeasure i would b greatfulll.. or any other ideas obviously ;p
