I remember well this old proposal of yours. But I'm afraid that it adjusts only to your own desires (not just yours though), and not to any logics and much less to any hint of evidence.

Why do you think about desires if talking about this? Obviously many Neolithic elements, which were not just from outside of Europe by the way but from local South Eastern Europeans as well, marched both Northwards and Westwards. There is plenty of evidence on this.
Now if the local forms changed in that direction of the Neolithic groups and stopped at a rather intermediate robust Palaeolithic-gracile Neolithic Aurignacoid final form, like it happened in the Nordid and Atlantomediterranid, Atlanto-Pontid spectrum, we can assume two possibilities:
The original population was pushed primarily or even only by the selective pressures in this direction by using the variation which was already present, since such Aurignacoid variants existed before there already. This happened for sure but in many regions or even in general it also makes sense to assume
that the newcomers had a significant impact as well. Even if there whole genetic input was rather low overall, some traits could be favoured over generations resulting in a genetically dissimilar and more local adapted but in the overall racial form similar basic type.
That is not speculative nor the result of "desires" but a reasonable assumption I'd say. Genetic and racial similarity is in my opinion not the same because the first is just about counting DNA, no matter which, no matter which function, the latter is about the more important aspects of traits determined by the DNA which had adaptive qualities and formed a biotype, a specialisation.
For sure you can find two individuals genetically close and racially distant as well as vice versa, because race is about genetic quality rather than quantity.
