The Green Goblin
I think he's asking from a legal perspective, not a practical one. Legally there is no reason why you can't do it, provided you're able to go straight outbound in the approach. If a holding pattern or sector entry is required, then it becomes the limiting height published for the holding pattern. Practically it may not be worth your while, however if the cloud base is reported between the MSA and your LSALT, then why wouldn't you descend to your LSALT to remove the need to do the approach? No one is saying do it right at 25nm, but you can plan that as your descent altitude. If fuel is that critical then there's something wrong with your fuel planning.
Legals aside, from a practical perspective - there are way too many variables to consider.
