How do we define 'small amounts'. Some sumps hold 3qts, others 7, etc. I don't think we can have it both ways. If additive clash may cause an issue in mixed oils, the risk of adding stand alone additives may be just as questionable. It may also be that too much of an additive could cause problems. If you are against mixing oils, i cannot see how adding anything to it is different.
One assumes a reputable additive company like LiquiMoly will only provide additives that synergistically blend with most stuff in motor oil. There is a small chance they could be wrong, but they test their stuff. Small amounts means try a half-dose to a full-dose only.
