The other way around is to swap out the rotors and axle bearings with 4 hole units, OR redrill the Tesla units to accept Lotus wheels., but that requires TIG welding the spinner to re-enforce the (new) bolt-lug holes.
Adapter plates won't work due to offset issues.
I have absolutely drilled these types of rim issues before for other vehicles. On occasion I have TIG welded the unused holes shut and refinished the paint.
It depends where the holes are as far as failure points. If the four holes are at the same diameter as the TESLA holes, the spacing will be acceptable as at least 3 bolts will be solid (the 12 O'clock is used as is, the 5 O'clock and 7 O'clock holes will be strong, and the 2:30 and 9:30 holes will be a bit weak.
If all 4 Lotus holes are at a differing diameter, then there is trouble and TIG welding for re-enforcement is necessary.
This is all IMHO. Your mileage may vary.
I guess I now need to find out diameter and spacing of Lotus Elise rims.
Best,
