No, I don't believe so. The process he used was a significantly more advanced version of the treatment that was based on a more selective genetic overwriting system that had a higher retroviral replacement accuracy and a more specific epigenetic footprint.
In essence, the 'latex' (which is technically more of an infectious cellular solution) was significantly more comprehensive and made the host a lot less goopy. If he *could* transfur someone, it would likely be through bone marrow transplant, or rarely a blood transplant, as his stem cells would still be epigenetically "young".
We can see evidence of this in the gas transfur scene in the ventilation system as one of Dr. K's failed attempts at creating the solution he used on himself. Notice how, in that, Lin's mind is still hazy, but he retains *some* memory, and he isn't dripping goo, but his tail is slightly amorphous
K was able to further develop the form retention, but in doing so he increased the memory loss, as seen with the snowy tiger transfur.
He was able to eventually develop that even further with the German-Sheperd-esque transfur that he used in the upper library hallway, which was capable of reliably transforming the subject, but also included manipulable neurology, which was VERY close to recreating the solution, although he'd likely have to de-variegate it as well
Evidently, by the time Lin and Puro escape, K is very, very close to recreating the solution, and the final incubation period of the pale virus is also almost up. It makes absolutely perfect sense that he would want Colin, who very obviously might have the pale virus, to stay within the facility until the treatment is finished, hence the gauntlet he puts him through. In addition, this also explains why he doesn't fear for humanity when Colin and Puro leave. He's so close to the final tests of the treatment that he'll be able to release the bunkered civilians no matter what those two do.
