Probably. I've tried it and this reintroduces the temperature drift to an otherwise-temperature-immune silicon device. I posted this in other fora at some point.
It doesn't do much except introduce leakage, but that's good for those pedals that are otherwise leakage-biased. It fakes yet one more characteristic.
For faking the noise that surface contamination gives, there are other tricks as well.
