You can buy a pick guard and use it as a template, they aren’t expensive but i suggest you get an actual fender tele guard to use as a template as knock off guitars often don’t fit the bridge plate, neck pick up of neck pocket very well. I build custom teles once in awhile and have had this issue a lot with different companies, as well as some knockoff teles have 5 hole, 6 and 8 hole guards for screw holes.
Pete is correct Teles and leather guards and full leather covers have been in style and popular since at least the early 70`s.
Waylon Jennings is a prime example of this as every tele he played was full leather covered. Tele plays are a VERY close nit community across the world and real real good leather work for covers and guards is spread fast and I often thought would be a very prosperous niche. Dragons I doubt would go over real good on a tele, it’s a "traditional" guitar and MOST, not all but most players are going to be traditional, you’ll not find a lot of shredders on a tele. You’re talking traditional country, blues, jazz, rockabilly and classic rock crowd. Not really your dragon and sword crowd. If you wanted to do figured carving, I just had a though of classic cowgirl WW2 style pin up girl would be huge if done well.
