As for the concept, seems perfectly legal to me - many systems have more than 1 bid to describe a given hand type.
While the concept seems legal to me as well, in practice simply stating 'we bid at random' is frowned on by regulators, because there is always the suspicion that you don't - you have some (possibly even subconscious) way of deciding which bid to choose. If you have a declared algorithm for selection which action to pick I think you'd be OK.
There's an English pair whose method of choosing which minor to open with 3-3 or 4-4 is carefully documented on their card and is something like (i) choose the better one if there is huge disparity between them, otherwise (ii) count the number of odd pip cards in the minor suits and open 1C if this is even, 1D if this is odd. {pips = cards from 2 to 9 inclusive}
