Can I stack multiple ND filters to photograph the partial eclipse?

I have a set of Urth filters at ND8 (3 stops), ND64 (6 stops), and ND1000 (10 stops). If I stack them can I use them to take photographs of the partial eclipse in the UK today?

I see people recommending solar filters that have a 16 stop reduction (ND10000), and if I stack mine I have the equivalent of 19 stops reduction. I don't mind colour shifts or some vignetting, but just want to make sure it's safe to do so. I am using a Sony a7IV.

I have seen this site saying stacking is OK, but would like to double check just in case: https://thefocalpointhub.com/blog/eclipse-photography/

Thanks for any help!
