TR Hardhead's robot mode looks pretty similar to Quake's G1 robot mode, whereas Wolfwire's robot mode looks quite different.
As you can see Hasbro didn't even need to do any retooling on Hardhead's body to make it look like Quake because the similarities already existed. I think the best you might be able to do with Wolfwire is retool it to look similar to Carnivac's G1 comic model. It would require retooling on the arms and legs to remove the "Weirdwolf-esque" elements and replace it with "Carnivac-esque" bits, which would be doable without affecting the core toy or its transformation. As for the robot feet, simply state in the instructions that the feet are flipped around so that Wolfwire's heel spurs become Carnivac's feet. Trying to make a toy-accurate or IDW-accurate Carnivac from the Wolfwire mould would be too difficult and you might as well make a new mould from scratch. But as far as retooling Wolfwire goes, I think that the Marvel Comic model would be the nearest match.
Btw, another G1 TF who transforms into a wolf is Sixshot, but he obviously already has his own toy.
He did mention Magnificus.I think that Magnificus might work. They've done far more obscure redecoes such as Universe Acid Storm and the G2 Stunticons. Magnificus' Titan Master would also allow fans to give Perceptor a toy-accurate head too.
The general consensus on an Obscure Transformer is one that has only ever appeared in one medium. As Magnificus has appeared in at least 3* media, this technically disqualifies as him as being truly 'obscure.' As more lesser known characters appear in newer canonical sources the number of properly Obscure Transformers dwindles. Which I think is good. I'd rather see writers include more formerly Obscure Transformers rather than making new ones up (e.g. Ironfist in LSotW etc.).
The G1 Reflector toy didn't even come out until 1986, and even then only as a mailaway exclusive! (as you know, but for the youngins readin' this)
I suppose the real challenge with Reflector is the sheer oddity of the figure. 3 robots who combine into a camera. The original toy transformed into a microfilm camera, but I wouldn't mind seeing a new one transform into a modern digital camera (similar to say a Canon DSLR or something). But of course, this would require HasTak to invest time and money to R&D the moulds that they really can't redeco into any other character. Unless say they did a toy-accurate version first, then released a show-accurate redeco later. Sure, some nerds would complain about the initial release and get enraged that Hasbro didn't release a show-accurate version... but a lot of people would buy the initial toy-accurate version. Then they'd release the show-accurate version and it'd sell like hot cakes.We've seen the same thing happen with CW Alpha Bravo/Quickslinger, Off-Road/Brake-Neck, and Rook/Groove. Some geeks may whinge about the initial releases, but it would work for Hasbro. They wouldn't do it the other way around otherwise the less popular versions would pegwarm.

*3 media:
(i) eHobby toy continuity; I'm counting both the original and Generations figures (and pack in comic) as part of this same continuity
(ii) Dreamwave's G1 continuity; although really as a background prop, and as TFwiki explains, since this appearance predates the first Magnificus toy, it's technically not Magnificus
(iii) Wings Universe
