Ciao Samrat,
It would be a packed 48 hours but yes, you could do it!
Since March 1st the combined ticket for Uffizi + Pitti + Boboli exists and is 38 euros in high season and 18 euros in the low season.
The pass in this case is valid for 3 days, so I would not do all of the above in one day and spread it out thus:
day 1: Uffizi in morning, then Boboli Gardens (and Porcelain museums, it is small) and Bardini gardens in the afternoon.
day 2: Accademia in the morning, then head back to Pitti Palace to see the museums within. There is the Palatine Gallery and Royal Apartments which are the main ones, then the Modern Art section is the next biggest. The Treasure of the Grand Dukes and the Costume and Fashion museum are smaller sections.
With the combined ticket, you can only enter each of the 3 "museums" once so this is why I suggest Boboli separately from the museums within the Pitti Palace.
