16 bits means a few MB of RAM and disk storage, that sounds ok. But I don't
get the real use of it. If you add one bit in the index and if it is only
used for 0.1% of the games in a base, it's a bit of a waste. Why not add an
extra PGN tag ? There is of course a performance hit but one can use the
user defined flag and then add his own free text. Then if you search for
games with both the flag and the text it is pretty fast.
