I wouldn’t say unachievable, there is almost certainly a way to do this, but it is definitely one of the more complicated views that ship with Pro and making tweaks isn’t something we’re going to be able to help you with via the support forums at this time.
Really I would suggest investigating this further with the help of a suitable designer/developer and/or making a feature request as we’d certainly give due consideration to a change of this nature.
If it helps, we could certainly provide a list of freelancers/independent developers who might be able to help?
