Solution for 2,200 lb Axle with Short Spindles to Replace Hubs with 5 Lug Bolt Pattern

My father in law bought a 4x8foot trailer with 4 on 4inch hubs with 12inch wheels. He is wanting me to change it to 5 on 4-1/2inch and use some 14inch wheels that he already has. I took one of the hubs off and it uses 1-1/16inch inner and outer bearings. The seal ID is 1.500 dia. The problem I have is none of the hubs on your site list the overall length of the hub from the seal to where the grease cap fits. The one I have measures 4-1/4. This is important because of the spindle length and having enough threads to tighten the castle nut. What is the overall length of this hub? Are all hubs a standard length? Will this hub work for what Im wanting to do? If not could you recommend a 5 on 4-1/2inch hub that uses 1-1/16inch bearing and 1-1/2inch ID seal with an overall hub length of 4-1/4
