Yes, I had a period of doing double bats on quilts and raised my hopping foot for that. Wasn't that hard to do on my Gammill, but I understand your hesitancy as I was worried about it too(first time). I have also used my 3lb rubber mallet on one of my own quilts (and early one) that had too many points coming together in one spot and I hadn't either pressed over the seams or could twirl them open. I just sprayed with water and but a solid surface under the quilt and hammered away on the "bumps" where seams met. Worked fine.
