Try building in more double stops, faux pedal steel bends, open strings ringing through and sweep picking into your leads... I always find those techniques add a lot of texture instead of just wailing on individual notes... you don't have to get too indulgent with the likes of sweep picking either... I know it can be a bit wanky but it's a great way to get from point A to point B with a bit more girth sometimes...
Could also be a good idea to try downtuning or alternate tunings... the opportunity to just shapes in a lead run to thicken it up would be good?

In terms of hardware I'd look into the following:
mk.gee
mk.gee has some thick sounding guitar tones... worth checking this out for some inspiration too...
