When starting out on a 5, you have to get used to...something. Either tighter string spacing at both ends, or much more reach and a wider neck, or some compromise of the above. There really is no way around the need to adjust - the only question is what to adjust to.
I have ginormous hands, and my 5’s have 17.5 mm spacing at the bridge, and a wider neck (1 7/8ths), but closer string spacing at the nut due to the extra string. I was clumsy for a while - that’s completely normal. A couple years in (I play 5’s about 80% of the time now), I’m at home with the compromise.
If you expect you can pick up a 5 and be at home on it in a couple weeks, I’d say that’s unrealistic. It takes far longer than that to develop enough muscle memory to play as well on a 5 as you could on a 4.
