Is a tele bridge pickup significantly different to a standard single coil
What's a "standard" single coil ? You mean a strat pup ?-)
But anyway... A Tele bridge pup won't fit in a strat without re-routing, but I don't know how it would work the other way round. If yes, a Sinner might indeed be worth giving a try, but I think I'd rather first give the Piledriver a try as far as I'm concerned. Now I'm not really into metal myself...

First, welcome onboard !-)
wrt/ the neck, I think you'd better first make sure your Tele is properly routed (FWIW, my own CiJ '62 Custom RI is not routed for a bucker neck). But well, if not you can always ask your favorite luthier to do the job, shouldn't be very expensive. wrt/ 'bucker vs SC neck, as I said, I'm not really into metal myself so I can't really provide any sound advice here (lame pun, sorry :mrgreen:), but there's also the 4-way switch option. This gives an additional position with neck+bridge series, which brings a standard Tele close to the 'bucker territory. I have this on mine, and even with very vintage pups (BGF50 here), it's really powerful and a great addition to the standard positions.
My 0.2 cents...
