Haven't played since legion. Is it still possible to "Tryhard" timewalking dungeons with old gear?

I remember having sets of gear with lots of gems, meta sockets, old legendaries/trinkets and so on for when timewalking rolled around. Stuff like using Pandaria gear during Pandaria or earlier timewalking weeks.

Edit: Thank you to those who replied!

With the way that levels and stats have been squished, is it still possible? Or would it be worse than using dragonflight gear at lv70?
