Excessive Mount Movement

Evening all,
I've got a Skywatcher 102 f9.8 achromat refactor on an EQ3-2 mount and I'm having a bit of an issue with stability particularly at high power. And yes I did buy it and yes in hind site I should have parted with the extra 150 odd dollars and bought the EQ3 with the s/s legs or the EQ5, but it is what it is.
I had a good look at it today and came to the conclusion that one of the main problems lay with the leg and mount base connection point, there are 5 fasteners holding the 2 aluminium legs to the mount base per leg assy(3 assy in total).
Now because the telescope is 1000 mm long, there is about 500 mm either side of the mount center any movement and the telescope acts as a big lever and the mount twists at the leg mounting points.
So I'm thinking if I cut a triangular piece of aluminium plate about 6 mm thick
I could extend the mount securing bolt and wedge the plate between the 3 legs about 150 mm below the mount base the same method used on the EQ3 and EQ5 mounts with the s/s legs. I think this will be a more effective method to deal with the problem than hanging a weight from the center of the tripod.
Does anyone has any other suggestions apart from buying a new mount?
