Well, you are talking here about a whole other use/need/application/cost which is not comparable to a DA 55-300mm lens, either version. I too have an f/2.8 outfit in addition to my HD DA 55-300mm f/4-5.8 lens, in my case, the DA* 50-135mm and FA* 200mm.
However, when I need to go compact, and in decent lighting, the single compact tele zoom lens does quite well enough for most situations. Considering this and the costs discussed here, I think the OP has made a fine decision. The DA 20-40mm f/2.8-4 is all about very high quality combined with compactness, a perfect match for the KP. Then for maximum cost effectiveness, combined with compactness and extended tele range, and very good AF, for this His 55-300mm PLM is a fine choice and a good matchup.

For sure in your first use, you will be happy because that is what your senses feels the best specially when the object is far off.
But in the long run - you will not like the acute angle of view of that two lenses.
He will have a continuously-variable angle of view from 20mm through 300mm, except for a 15mm gap between the two lenses. There would be a much greater gap if going with a tele lens staring at 70mm. A future acquisition of a DA 15mm Limited, or a DA 12-24mm would broaden this FL range even more. This current kit is good for most practical needs, with fine quality, and for finding out about the application of different angles of view (FL with APS-C). It is unpredictable as to what his general preferences will turn out to be in the future, if any. My own photographic interests have turned out to be quite varied, therefore so must my tools be, which is of course at some expense!
Eventually, there might indeed be a future need here to consider having the fine, very versatile DA 18-135mm for times when carrying a singe lens with good range and reach is needed. It is for this reason I have both lenses, the 20-40mm LTD and the DA 18-135mm, and get good use out of each of them, according to the occasion. The 20-40mm LTD is one very fine, beautiful little lens!
