This is edit is what I think the mane six should look like after the timeskip, I removed the lines under their eyes and grey hairs because it don’t look right on them and parents did not have that at all and their parents looked just as young as the mane 6 pre timeskip and I hate seeing rarity having grey hairs and they should be looking younger. See them looking old did not sit well with me and made the redesigns feel uneasy to me and made me feel mixed about them, I also removed the hairs that looked out of place on applejack, remember this was made to be a fun fan edit and when I make art of the older versions of the mane 6, they will base of my version of the mane 6 you see here.
 
Note: this is the first screenshot edit that I made and I did not want to edit spike or twilight because they look perfect to me
