Shifter Ergonomics for Larger Hands

First post! Really enjoy reading this forum as it has a ton of good information on gravel cycling.  I have two Donnelly carbon gravel bikes but the indoor trainer bike has campy record and my “racing bike” has Ultegra Di2. I built the racing bike with Ultegra Di2. over a long gravel ride, mechanical shifting becomes a real strain and energy expenditure. But the advantage of campy is the brake hood ergonomics are more comfortable over the long haul, especially that my hands are on the larger size. The R8070 shifter body seems tiny by comparison and do not “fit” as well. This becomes its own strain on a long ride. Shimano offers many options & combinations within their Di2 range. I currently run 8070 hydraulic shifters with the 8050 front and clutch rear derailleur. My question is: Are there other shimano Di2 brake shifter options with larger brake hoods that will offer “better” ergonomics over Ultegra 8070 hydraulic shifters more comparable to the campy shifters? I’ll consider another option that has just a larger shifter body...
