Yes, I just welded a pad about 3/4" larger all the way around than the stock pad. I used 1/8" steel.
But you have to becareful not to make it so that it interfers with the center stand lever.
It has worked very well and I never know it is there except when it is needed.
I never had concerns about the lean angle of my side stand. I did however have issues where the foot was sinking into hot asphalt. I had a Trumpet drop through poor pavement once, and didn't want it to happen again. To remedy this, I also added a pad to the foot to enlarge the area and spread some of the pressure. I took the original foot, held it on a piece of thin cardboard, and pushed a washer up against it. I placed my pencil inside the washer and dragged it around the foot, with the result having enlarged the foot with precise proportions. I cut the cardboard template out, transferred it to my plate steel, and ground, and filed it to shape. I then located the new foot forward of the stock foot to give me the needed clearance when in the up position. I welded the pad, ground and shaped the welds, and rattled some black paint on. Looks like it was meant to be there, and serves the purpose. The thickness of the plate is not critical, and the size of the washer I used created a foot that was about 3/8" larger all the way around.
