something else you can try, it's been done on bushies and is fairly common on tribals. Its also what Zenitram blocks on 2003 BKO's allow you to do.
Put a volumizer on your Bushy where the LPR normally goes. A 2002/2003 BKO AKA Mitey Max is perfect. Then you can drill and tap a hole in the front of your inline ASA (use the same size hole and threads as gauges use) and screw a cocker LPR into it. Like a microrock or something. Actually, FGP's work well because you can put the air barb on the front of the LPR which is easier for this setup.
Thats the basic idea of what you're gonna be doing. Now here's all the smaller tasks you have to do to make it work.
-plug up the hole in the gun body's LPR threads that allows the LP air to enter the gun's internal LP air passage. Not totally sure what to use, probly some kind of epoxy.
-Next, you need to drill out the front of the internal air passage and thread it for a 8-32 barb so that you can connect an air hose from the air passage to the cocker LPR. Or, if you have an older Bushy that has a grub screw, simply remove that.
Here's a couple pics of what it looks like on a Tribal. Its exactly the same on a Bushy.
