try not playing a caster for once and the progression wil feel exactly the same as from 11 to 20 :^)
realy progression doesnt feel satisfying if you dont start at level 1.
And a 1 to 20 campaign would mean a LOT of level ups fast.
The only way to do this , without the DM giving you XP for everything, is to have a VERY combat focused campaign.
by which i mena somehting like ToEE where youre constantly beeing thrown enemies to fight
