How do you feel about some Nydus upgrades?

A while ago the Nydus worm got some serious nerfs that included a cooldown on nydus worm creation and being able to attack nydus worms while burrowing in. And while I mostly agree that these nerfs were a good idea. I sometimes wonder. What if they simply made some of these upgrades? Similar to my thread about medivac upgrades I have some ideas for Nydus worm upgrades that each come with downsides and are branching upgrades. Basically you pick one and the other two are unavailable.

Quick disclaimer: Obviously none of these are actually gonna happen, but theoretical discussion of ideas that could be in multiplayer is fun!

  1. Molten Jaws
    Nydus worms take 50% less time to emerge when placed. However all units that exit the nydus worm from either exit point loose half their health and get a permanent debuff that reduces maximum, health and damage by 50%.

  2. Creep Fiend

Nydus worms now spread creep within a range of 25 from the vicinity of the created nydus worm, but Nydus worms become a one way affair. Any unit passing through a nydus worm cannot exit back out the same way. Only the original network.

  1. Gigantism

Nydus worms are now twice the size of normal Nydus worms, have 50% more health and unleash a shockwave that damages nearby structures for 50% their maximum and knocks nearby units back. However Nydus worms now take 50% longer to finish burrowing in, cost 250/250 to place and non massive units exiting the nydus worm take 50% longer to exit in que.

Like last time, upgrades can be changed but it each time someone changes upgrades it costs at an extra 50% more then starting, And the starting price for these upgrades is 145/145. Only one can be active at a time,

Do you think upgrades like this would be a good idea? Would any of them have a good place in SC2 multiplayer or would some of gthem be too OP or not worth getting?
