conversion requests

I was wondering,i dont fully know what the rules with conversions are i did look in the rules for modding requests but,  if someone would be able to convert some sims 2 cc for sims 4 there are a few things here and there that i used allot in sims 2 and would be nice to use in sims 4, these would be for personal use .

• Papaver's Poppies: in sims 2 theres this set of poppy flowers in square and triangle shapes and i would like to get them in sims 4. Their shape is great for landscaping and the colors are soo bright and great for witchy lots. 
• Tom Thumb Nursery, modthesims.info/d/257889/tom-thumb-nursery-quot-once-upon-a-time-quot-8-new-meshes.html?cb=1596395298 i used these allot in sims 2 and the changing table excluded since sims 4 doesn't have those, it would be rather neat to get them in sims 4. (i have sent the creator a request, asking if i can get permission to have these converted and i do hope for a response but i doubt i will get one as their last activity was back in 2013, their rules say nothing about conversions so im not entirely sure what they would think of that. ) 
• Klinny cage pets: modthesims.info/d/229104/new-pet-pet-cage-one-eyed-alien.html  https://modthesims.info/d/231705/new-pet-pet-cage-mini-dragon.html https://modthesims.info/d/230041/new-pet-pet-cage-mini-piggy.html " rel="nofollow" target="_blank">modthesims.info/d/235393/new-pet-pet-cage-one-eyed-plant-creature.html modthesims.info/d/229104/new-pet-pet-cage-one-eyed-alien.html  https://modthesims.info/d/231705/new-pet-pet-cage-mini-dragon.html https://modthesims.info/d/230041/new-pet-pet-cage-mini-piggy.html  im not sure if these can be converted? but if they can and be treated like the hampster creatures it would be super cool to get them.  (Again i did leave a private message asking for permission to get them converted but they have not been active since 2015 and im hoping it would be okay with them if only the conversions aren't like shared? if its for personal use? recolors are okay with them as long as they receive credits so im hoping that conversions would work the same.)
