Unfortunately, it not possible to automatically load two elfs on boot. Although, there are a couple modified cbhc on here somewhere that do allow having two separate options for loading elf files you can only auto boot one.
However, there is the WiiUPluginSystem which can be auto booted and does support both Padcon and SwipSwapMe and a bunch of other stuff like SDCafiine (game mods) and a Screenshot Plugin. When launched, you just have to choose which ones you want (it won't remember) and then you enter the button combos (also have to do this every time) and bam you are in. Here is the Discord with download links for it and all the plugins:

Couple things to note however is that it will automatically load into the first user on the console. Although you can make a user a default user by clicking your mii on the home menu and scrolling down. Also, the homebrew launcher will launch everytime you load Mii Maker (just like with the browser exploit) so just quit out of it to access Miis. If you want to change your user Mii however, doing it normally will take you to homebrew launcher and then to standard Mii Maker, not edit User Mii. In order to edit your User Mii you need to reboot and enter Hakchi menu and load System Menu manually.
Also it's always loading Hakchi, all hakchi features like custom apps and "backups" and all that still work. The only thing the Mocha option does is load the elf file that is named mocha.elf. It doesn't have any effect on functionality.
