Highly unlikely. Sure they'll strengthen in the summer, but still the calibre of player they can get is a lot lower then city, arsenal, Chelsea, united, Liverpool, spurs, etc.. Look at when Blackburn won the title back in the 90's. They came out of nowhere, had a great year then went back to being nothing special. This is a team who went from on the verge of relegation to on the verge of the title. These seasons are rare but do happen, and o can't think of a situation where they didn't revert back to the norm. In the long run, money always makes its impact and there are plenty of teams with more money then Leicester.
