I liked your reasoning and everything made sense to me.
I have done this once and if i should do it again i would go with a trtdose, 100 mg prop f.i. 250 sus, isnt that a bit high? You could end up in the 1200-1500 range and im using sus now and sexually it hits rigth away but its surprisingly slow when it comes to anabolic behavior.
150 mg prop is the limit ive red. With that the body will not increase hct, but i ended up in the 1100 range with 150 mg propionate ew and then i guess it will cause some androgenic sides and some e2 shit aswell.

For sure u cannot run lgd as a standalone but i have never considered hcg as a solution. Maybe some more experienced members could discuss hcg vs trt-dose for a lgdcycle.
