A split bucker will never replace a single coil, they just don't have all of it, if that is what you want. There is extra magnet pull and other stuff, fields are also different. You will want a pretty hot bucker, so you can at least split to moderate output (I don't like to mention resistance as output, as it isn't but 12k + Alnico V or something should do it). You would want to split to the bridge coil, it is brighter (but quieter). If you get an on/off/on switch you can wire it to north coil/series/south coil and get all the above options.
Then you can consider the effects of the bridge plate typically on a tele on the magnetic fields, this can be mimiced with extra plates/ bass plates if you are clever though (SD custom shop is).
My preference for brightening a humbucker is generally parallel mode though, not splitting. The output difference is less drastic but still large and brighter. I can get spank out of both split and parallel coils well, but a lot of that is technique, I hybrid pick a tonne. You need that SNAP.
As for a tele with a bucker, ain't a tele no more. Just a single cut
