It could be done that way, but not with the existing fittings. The spacing would need to be changed. The one other thing to consider it that the two pieces of spar should not be butted hard together. There should be enough gap to ensure no wood-to-wood contact when the spar is loaded. That condition would affect the stresses in the wood around the bolts. Best option, keep what you have. Next option is to do a re-design of the fittings.
