html - Is it possible to add just one page to existing sire project via PUG when the rest is written in simple HTML5?

Question

So I have a simple site at hand, written with HTML5 and Less CSS. Now I have to add a market-page to it and I found a comprehensive guide on how to do that with ExpressJS + PUG + MySQL.

But before I do that I would like to know whether I'll have to convert the whole site project into new structure or I will be able to simply add a market page to already existing project without generally changing it?
