Aligning of icons?

I've been fiddling a bit with a separate menu and realised that the look would benefit at lot if I could somehow align the icons Y-wise. I run a taskbar of two rows and the icons seem aligned to the top, whereas I would like them to be centered. Is there a neat way to solve this? I don't mind if I have to customize the plugin graphics to give them an offset, but if there's a smarter solution I'm all for that.

Yes I know about this problem. Currently every plugin control position itself. I'll move this under TLB control and there will be the alignment option.
