I do not know of an easy / clean way to make up short distances like
that w/o disassembly of the system.
Sounds you'll have to Rube Goldberg it in again; you might consider
Toro Funny Pipe (barbed fitting poly pipe) on the downstream side of
the valve & stuff in a service loop to make your connection. You can
screw in the fitting & then shove the pipe on
http://www.toro.com/sprinklers/pipes/index.html
I use the stuff to "move spriklers" or install extra heads.
When you rebuild / replace the manifold I suggest using Champion
sprinker vavles
I use them in all my sprikler valve installs
Champion red brass atuomatic anti-siphon valves with unions

If you don't want electrical control

the electric autators can be added later, if you want
The anti-siphons are a little more expensive but protect the water
system from backflow contamination.
The red brass valve bodies will last a LONG time, the valve guts can be
replaced & the electric autators .can be rebuilt or replaced easily.
I've got some that are approaching 30 years; repalced the solenoids a
few years ago & a couple of actuators before that.
A mainfold setup using these vavles will allow the change out of a
valve in just a few minutes (just make sure you allow enough swing
clearance between valve risers U& use the vavles w/ unions)
I'm not a huge fan of in-line valves; change out is harder & the
anti-siphon feature must be plumbed in seperately
