Orchid compost is very specialised. Very liitle nutrient, very fast drainage, a bit of localised moisture retention. You will gain little by blending it off. Perhaps an epiphylic fern.
location: Surrey Hills, England, ex-woodland acidic sand. "Have nothing in your garden that you don't know to be useful, or believe to be beautiful."
It's great for aroids like climbing philodendrons, or other epiphytic houseplants like Hoyas, Rhipsalis, Stag Horn Ferns etc. Typically you mix it with MPC and perlite/grit.
