I don't see any problem at all wiyh cutting up mint sets to get the coins you need for your collection & as you say selling off the coins you don't want is good too,gives you money for thing you do want.
We have one member here who I don't think owns anny coins that are still in mint packaging,he pulls them all out & puts them in 2X2's,each collectors has different preferences to how they want to store their coins & it's up to you how you want your coins displayed,if you think it looks good go for it.
