Without careful consideration I would say yes, but the problem may be the authentication of the document. How will you protect your HTML page? PDFs were created so that they looked like you needed them to, font size, placement, font style, etc. And it is easier I believe to apply a digital signature to them which secures the document from alteration. Can you do that with your HTML page? If not, I would say this is moot.
I would say that for low risk issues, HTML E-Sign agreements are already used, "Do you agree to the terms of use..." as an example.
