Changing the existing DKIM specification is probably a big challenge.
Yes, but it can be done as a separate specification that is classed as an 'update' to the DKIM spec.
fwiw, I've heard rumors of some industry folk wanting to produce "DKIM 2", but the rumors have carried no details to indicate what the substance might be.
Another approach could be to update the wip BIMI specification with a statement that a DMARC pass must be ignored if it is solely based on valid DKIM signatures with length attributes.
Please no. There has been some tendency to effect a change in an underlying specification by adding a constraint onto a specification that uses the underlying one.
The result has been basic modifications to email, without changing basic specifications.
Note, for example, that DMARC has broken the From: field, so it now serves as what the Sender: field was designed for.
