My question to you: is there any significant performance issue? Are you planning to update your applications that may require updated kernel?
If your answers are "No", then I would say let the things be as they are now. 2 years of uptime is nothing, Linux on rock solid platforms like Power, can give uptime of a decade if there is no patching/upgrading of software or hardware.

ctrlaltdel
CTRLALTDEL(8) Linux Programmer's Manual CTRLALTDEL(8)
NAME
ctrlaltdel - set the function of the Ctrl-Alt-Del combination
SYNOPSIS
ctrlaltdel hard|soft
DESCRIPTION
Based on examination of the linux/kernel/sys.c code, it is clear that there are two supported functions that the Ctrl-Alt-Del sequence can
perform: a hard reset, which immediately reboots the computer without calling sync(2) and without any other preparation; and a soft reset,
which sends the SIGINT (interrupt) signal to the init process (this is always the process with PID 1). If this option is used, the init(8)
program must support this feature. Since there are now several init(8) programs in the Linux community, please consult the documentation
for the version that you are currently using.
ctrlaltdel is usually used in the /etc/rc.local file.
FILES
/etc/rc.local

AVAILABILITY
The ctrlaltdel command is part of the util-linux-ng package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.
