No problem. If you were still set on doing something else for the brief time you are in Malawi, you could check out Liwonde NP for a quick Safari (just south of the lake), Zomba plateau area for hiking, or further south to Thyolo / Mulanje for the tea estates. It's quite the varied landscape. Hopefully Chileka Airport in Blantyre will be back at full operations next year and then it would make sense to fly out from there.
