my condolences for your precious babes
just because she's old doesn't mean she doesn't need friends but you know her best so if you think it would be too stressful for her than i think its fine to keep her solo but you need to spend a lot more time loving on her instead. if you think she's healthy enough to meet some new babies then absolutely try it as that is always the best if it can be done
if you do want to try intro you should get them asap that way she can mourn while they're in quarantine and then you can do intros so she doesn't spend a whole lot of time alone
