Rather than altering script grammar rules, can we handle these exceptional stuff with ZWNJ/ZWJ? I am agree with jonathan, that it is mostly right hand side of words which gets elongated. So i think might be with Regular syllable one can simply use ZWJ and append as many matras as he wants. That will be ultimate solution. At least in Devanagari i have not seen syllable having more than single matra other than Comics stuff mentioned in this case.
