I have a set of Flat 52s in a Tele. The neck in that set is very similar to a Strat.
Or, drop a Strat pickup in as previously mentioned.
Absolutely, the Flat '52 is going to be your best bet for a more Stratty vibe from a traditional Tele sized coil, especially if you avoid the chrome covers (chrome uses a brass cover blank under the plating, which rounds off the treble response a little, so any other colours, or completely uncovered will give you the most "spank").
Teles are great for mixing and matching pickup types too, as you often just need a different pickguard, since most modern examples have oversized neck pickup routs to cover multiple models with different pickup options. Be aware, though, that a normal Strat coil will be out of phase with a normal Tele bridge, when you run them together, so you would need to specify what the final setup was going to be if you ordered a Strat pickup from us, to be sure that we build it to match. Having said that, an out of phase middle position on a Tele sounds cool as heck IMO!
