Deck to Flybridge ladder ideas

[StratPlan61]

I have never liked running between my aft deck and the flying bridge as I manuever the Whaler up/down on the davit. Bear in mind I do not have an aft deck ladder-up, I must run through the salon, into the pilothouse and up the ladder, back across the flybridge, climb over the weatherboard, etc. So I have often thought about installing a ladder between the narrow starboard side deck, outside the weatherboard, up to the flybridge deck alongside the davit.
I think I could buy a super-long pin-in style ladder from Marquipt like I use to board the boat sometimes (a 4 step). I do like the thought of it being removable. I also thought about scrounging another ladder like the swim platform-to-aft deck ladder I have. Probably wouldn't be quite tall enough. Maybe a narrow fabricated ss ladder from one of the custom fabricators? Very few would ever use this ladder, no kids or anything like that.
What are your thoughts?
