Yes there are allways other options, but sometimes not so cost effective:-)
You could piggyback the two smaller cylinders on top of each other but one turned end for end is one way.
Another way is the exponential steering like 52JDeereBguy mentions. But it would require some machineing and you do run the risk of overpowering the spindle or axle and breaking it since it may not be designed to handle the stresses imposed at certain turning positions.
Some of the old 3 wheel swamp buggy fert spreaders used a hydraulic motor and chain and sprockets to steer. I dont like that setup much. I ran one and it was'nt the most confidence inspiring experience. But your current hand pump would run a motor just fine.
Another way to utilize the 2 cylinder idea is to put one in place of the existing cylinder and then fab up some mounts to put the second cylinder on the cross tie rod. But you would have to make sure cross tie rod travels the same distance as the main cylinder does.
Or, you could even put both cylinders down on the cross tie rod. Each one facing the opposite direction. This is probably the most common way to do it, but make sure you keep the cross tie rod installed to keep the cylinders in phase and your toe in constant.
