Will I regret skipping Porto to Vila do Conde?

Hi all,
I've spontaneously decided I need to do a Camino this year and since time is short (and I'm not Primitivo fit) the Portugues looks like the ideal option. I'm only interested in the Coastal (at least until Baiona, at which point I'm told it gets urban).
I have 12.3 days and would like to make it to Muxia this time (both my Spanish Caminos ended in Fisterra). My favourite parts of the Norte were the Coastal bits and so I'm asking myself if I will regret taking the Metro out to Vila do Conde to reduce the pressure or whether I should instead do the Coastal walk around Porto and find another spot to perhaps skip 10-20km by bus later in the walk...? I'm quite happy to do 25-30km days if needed but will be starting my Camino at around 4pm after a remote working day, and as we all know, stages aren't always neatly divided into the km range we'd like on a particular day 9 days from Porto to SdC is doable but not the most relaxing of holidays

Edit: To be clear, I have previously done the walk to the airport from the Cathedral and can do Porto-Matsinhos after work one day *after* the Camino, for example.
