This is possible but I wouldn’t recommend it as it would open a door for Satan to make you feel boastful. People will know that you want to pray more at home.

It is best to offer witr with the Imam and then you may pray as many as you want at home without repeating your witr again.

As we pray taraweeh and witr in the masjid with imaam, i couldnt actually pray tahajjud after a small nap as i prayed witr with the imam. so can i have intention of praying taraweeh when the imam praying witr and after the last one rakah tashahudd can i complete it as a two rakkah taraweeh and go home and do the tahajjud and witr with my convinience?
