Good point about taking 1/2 position off the table. Personally I always approach each trade as it's own trading style, so I never change a daytrade into a swingtrade (though if a winning swingtrade moves quickly in my favor, eg during day 1 of the entry, I may often close it to take profits, or at least close part of the position).

Losing daytrades should never be 'converted' into swingtrades, as that more often magifies losses and stops. Each trade should be entered on it's own timeframe, with it's own specific technical pattern reasons for the entry, and timeframes/targets/stops.
