Yes, yes, yes! You do not have to go custom. The industry is responding to the needs of those like us. The only difference is that these bikes have compact doubles. It is fine, believe me.
My Trek Silque has an Ultegra rear 32, road derailleur (although I had to have a a 34 mountain derailleur put on my custom Guru, as it was before they made lower road gears) and now they make a 34 rear road derailleur. There are Silques at many price points, so you have to really research to decide what you want. I have 47 cm, with a short top tube, WSD narrow bars (although I swapped the Trek bars for Specialized). It is an endurance road bike, so more upright than traditional race bikes. The 47 cm has 700 wheels and I have never had toe overlap. I cannot say enough about how happy I am with this bike. Before I got the Silque I had swapped my rear derailleur on my Kuota from a 25 to a 27, then to a 28...
The Specialized Ruby is very similar and also comes in small sizes.
