The complexity comes from having to align the instructions somehow - you'll need to recognize this pattern at different offsets in each fetch and realign instructions to decoders based on it. You'll need to correctly handle multiple overlapping matches and partial matches at fetch boundaries. Then each decoder will need wiring for 3 instructions rather than 1 and emit a wider micro-op with the extra immediate.

My question is whether you have any actual data that suggests burning 27 bits of your encoding space on it and adding fusion is really worth it? Good ISA design is all about measuring frequencies of particular idioms and only adding instructions (or uarch optimizations like fusion) where the improved performance is worth the cost. Modern cores mostly fuse compare+branch since those instructions are extremely common. 64-bit integer immediates simply aren't common.
