Could the wing allow supersonic speed?  Considering the problems IC powered aircraft had approaching mach 1.

What a shame the model was lost :( I think Tupolev museum has the model of the initial Tu-2000 configuration. That drawings are not public was to be expected though.
For this comparison the Tu-2000A is more relevant anyway since it's clearly influenced by the original du Pont design (which has no resemblance to the final NASP configuration either).
Hopefully we can have a NASP a202 / Tu-2000 comparison some day.

These are only two images that left of that model. Model itself was lost either during Tupolev DB relocation or was given to MATI and stolen there.
Drawings are still classified.

The problem is the final configuration of Tu-2000 was very different from the early concepts shown to public.

I'm aware of that. If one only could have three-views of that configuration (or more images of that model)...
(Another one from buran.ru attached.)

Trick question, none of them are realistic.

Finally some comparison views of both vehicles. Note the size difference, though no exact dimensions for the "Government baseline" vehicle are available. Takeoff weights 36,000 kg vs 70,000 kg. Which one is more realistic? ;)

The Tupolev Tu-2000A was to be a demonstrator of a single-stage to orbit spaceplane comparable in function to the US X-30 vehicle. Development started in 1986 as a response to NASP.
Length: 55.5 m
Wingspan: 14.0 m
Height: 12.25 m
Empty weight: 40,000 kg
Take-off weight: 70,000 kg
Propulsion: 2 x D-100 turbofans (Mach=0-2.5), dual-mode scramjet (Mach=2-20), 2 x liquid-propellant rocket engines (Mach>=20), all using slush hydrogen fuel.

My 3D models of two comparable 1980s SSTO projects:

This one is meant to represent the "Government baseline" vehicle that was the end result of the $5.5-million COPPER CANYON study program run in 1984-1985, and input for NASP Phase 2. It was scaled up somewhat from the initial "du Pont baseline" which was to be an "F-15 sized 50,000 pound (22,700 kg) vehicle" to an "SR-71 sized 80,000 pound (36,000 kg) vehicle". Propulsion was provided by du Pont designed engines using a scram-LACE cycle. Payload 2,500 pounds (1130 kg) to polar orbit, propellant mass fraction 0.54, Isp 1,400 s, delta-V 47,000 fps (14,300 m/s).
