I beleive you can by the reluctor arms at Summit (don't have a catalog here at work though, to confirm). What's you're compression ratio? 38 deg. should be ok with less than 10:1 compression.
I have my timing set up very similar to yours. I'm running an initial 15 with the 13L reluctor for a total of about 41 with no pinging. This is on a stock 289 block/heads with Performer RPM cam/intake.
I would think your idea a piece of hose over the reluctor arm stop would work well for limiting the total advance. You'd just have to use a timing light to see where you're at and whether you need a thicker/thinner hose.
If you always do what you've always done,
You'll always get what you've always got
