Nope not with visual coding.
You need custom dsp for this. You can do those processors if you get hold of c++ stuff to plug into Hise, or get a developer.
Autotune and good reverb is the kicker.
Both of those are 'life's work' type effects that take years to develop from scratch, and so nobody likes to give out their implementations of those for free.
Megaphone effect you can do in default hise using the built in convolver if you're willing to use convolution. EQ can be done that way too, or using the stock hise EQ (It's not an amazing eq I don't reccomend it) but it would work.
I'm a perfectionist so take all of the above with a grain of salt. Maybe there is a mediocre but easy way to do it that I've never considered. But I'm fairly confident that you're out of the scope of the built in hise modules. 100% Definately out of reach if you don't want to code at all.
