How did the front element come to be missing?
I am not familiar tith the non is version but the other one is very expensive. I wouldn't use one with no front element because you will get dust and dirt inside it.

The answer is no it will not work. The front glass is part of Lens Group 1. Why would you even think Canon would put lenses in their lens that is doesn't need?

"ive been told that it is just a plain glass element NOT an optical element on the mk1?"
It may be but I count 10 lenses in 8 groups. That tells me it is needed.

Even plain glass has a refractive index. Even if the element's only purpose was to have coatings painted on it, the rest of the lens may have had to account for its presence.
And why isn't the element there anyway? Doesn't its absence suggest that the lens has been dropped? So what other damage might there be? Unless you're a qualified lens repair person with considerable experience on Canon lenses, I think buying it would be a very risky proposition.
