I assume you’re talking about FPGA Ad Astra? https://projectf.io/posts/fpga-ad-astra/ https://projectf.io/posts/fpga-ad-astra/ The first sprites post, https://projectf.io/posts/hardware-sprites/ https://projectf.io/posts/hardware-sprites/ does include 4-bit sprites, but again no overlapping. I am planning another sprite post with overlapping coloured sprites combined with a framebuffer background. I will probably use approach 2, as you describe, but with hardware design, I’ve found that the best algorithm can surprise you in practice.
