Of course, why not? Then you can hire other people to circumambulate you, and you can give them tea and biscuits or ice-cream, depending on how long they have been circumambulating you.
Anyway, yes, you can wear these, also the mantras can be recited. Please make your life most meaningful with the thought of bodhicitta.
With much love and prayers...
