Not quite Doh as you think
You can upgrade your shocker to the new board, but you then require a new grip frame and trigger etc approx cost £200 odd plus vat
Or you can change the trigger frame for IPB WERM frame or a HSW Hyper frame, both these frames mount a LS switch behind the trigger and you then solder wires to the Ds board.
The WERM is about £150 odd including VAt etc
the Hypersports is about £180 including Vat etc
I have a WERM on mine and combine with a Delrin bolt its makes the gun so much nicer and easier to shoot.
Im going to be at the next MM at Jamies if you want to give it a try
cheers
