Replace circuit breaker with slimline

hi all,
I am finishing my basement and definitley needs more circuits for receptables and lights there. Unfortunately, the main service panel(Challenger SB10(20/20)) is already full of circuits. I am thinking of replacing two 1" 20A circuit breakers with four 20A 1/2" slimline breakers. As a biginner when it comes to electrical, pls advise me what to take into consideration especially safety standpoint. The panel's max Amp is 100 and the type is 120/240 v.a.c.
Please email me at

Your panel is only listed for 20 breakers and is not listed for slimline breakers.
