ADD MORE ITEMS ON VILLAGER/WANDERING TRADER'S TRADING

i really like to do a minecraft challange especially the survival one ex: skyblock, etc. currently im trying to do survival on flat world on minecraft bedrock, both java and bedrock have different mechanic, but what i want to emphasize here is structure generation, bedrock didnt have any structure that will spawn on flat world, that will make us harder to progress, so im suggesting to ADD MORE ITEMS ON VILLLAGER?WANDERING TRADER TRADES, items like they should sell lava or any essential items that can help us progress on this kind of challanges, thank you. you guys should add grass block crafting recipe too thou
