No matter what you do, if you leave the shift linkeage in the factory configuration (i.e. all the joints still there, with reverse lock out still functional) you pretty much end up with a shifter that is still a few inches rear of where it would be on an SR/KA trans.
The only people i've seen come up with a solution that looks to be shorter is GK Tech which is not in full production yet.
There are things you can do to shorten the assembly up slightly more than just cutting out the linkeage and welding the two brackets to each other, and I went over them a little in a thread I posted awhile back.
