Yeah, you can thin it down with humble mineral turps.
Over several builds i have done things slightly differently and reckon best to lay at least 6-8 full strength coats before initial 1200 grit wet sand. Not so sure about applying TO with wet & dry paper as it can leave multiple uneven layers that only show up when doing a robust wet sanding session.
From 8th coat i would suggest adding a few drops of turps to a small amount of TO to slightly thin it down as my previous 50:50 ratio was too watery and prone to introducing runs. Once you have done 12 time for 1500 wet sand and then next couple of coats done full strength. From here, just alternate a couple of full strength followed by slightly diluted, then wet sand with 2000 grit from coat 16 and up.
Somewhere around 20 coats it will feel smooth and hopefully have enough thickness to sacrifice some layers in the final sand & polishing process.
Sounds like a lot of work but much quicker and easier than using DT.
