Or, with no ECL problems, you could be a barghest and get leadership, getting hundreds of extra HD from all those followers and cohorts that you eat.
If you need a fly speed, give the thing the air element template from manual of the planes, which gives extra dex and a 100 ft (perfect) fly speed. The dex will also help initiative.
For SR, take celestial/fiendish(?)/some other template that gives SR, or take 13 levels in monk, and the rest in forsaker. You can probably get up to SR in the 50s or something (you can at least get sr 45 this way, which will be tough to beat by any caster that doesn't have 26 levels or 22 levels and spell penetration). There are some creatures that have spell immunity to a handful or to all but a handful of spells...most notably will o' the wisp...and this could probably be abused quite easily. (perhaps a barghest who has been feeding for a while, shifted into a will o the wisp?...oh, and if you take will o the wisp, why not just get a spellsword that makes you immune to those other few spells, so that you dont have to worry about that either)
For initiative, you could always take iaijutsu master from OA to get chr to initiative, and also use kaupaer's skittish nerves (+5 init, magic of faerun) for an extra boost.
I think your best bet is to just be clever and try to look for something that other people might not notice. A lot of people will figure out how to get high DCs, massive strength, massive initiative, lots of prep rounds through time stop, etc. etc...but if you come up with something neat like the pixie in the backpack or 100-armed gestalt horror, then you probably have an okay chance of pulling off a win.
That's about all I can think of for now....
