Hi, you are after quite a variety of tones, as Hendrix had late 60's Strats, Mark Knopler, Chris Rhea and Stevie Ray all have early 60's, Clapton and Eric Johnson have 50's. All of them have different pickups and the capacitors were different from the 50's to the late 60's. I have Apaches (with and without baseplates), Mother's Milks, Slowhands, Irish Tours, Sultans and Sinners in different guitars (some in HSS sets), and even they give different tones based on the woods .
To add to it you have an SRV strat (which I thought had a pau ferro fingerboard not ebony?). You could do a mixed set, an Apache neck will get the sounds you are looking for, the Mothers Milks are a little brighter and would perhaps suit the middle, and getting RWRP will get the notched 'in-between sounds), and for the bridge I would again look at the Apache or perhaps a Slowhand if you want a little more mid push.
As a single set, I would go for the Apaches, they will give you the best strat tones out of the box.
